Halite - Salty Mystery of LIfe
Rarick, R. Dee
Salt is vital to nearly all living things and has been almost since the
beginning of time. Men and other animals need common salt to help
maintain a critical chemical balance in their bodies. The blood and
other fluids that bathe every cell of our bodies consist basically of a
salt solution of almost the same proportion or composit ion as that of
sea water. Salt regulates the exchange of water between the body's
cells and their surrounding fluid, which carries food in and wastes
out. When the first vertebrates crawled out onto the land to stay,
these internal saline fluids enabled them to survive in that strange
new environment. Salt is necessary for life. Without it man and all
other animals would die.

Pages from the Geologic Past of Marion County
Judah, Robert E. (Illustrator); Harrison, Wyman
The "pages" of rock strata that together form the geologic history book of Marion County are written in a foreign language of fossils, rock fragments, and mineral grains. We are able to translate the messages from these accumulations of extinct organisms and lifeless mineral matters through the knowledge gained from efforts of many generations of geologists. The meaning of the story of earth history that arises from the work of thousands of geologist translators lies in the connections man finds between his life and the
world around him.

Adventures with Fossils
Shaver, Robert H.
Many laymen write to the Indiana Geological
Survey and ask: “Please send me books and maps on fossils and where they can be found.” Some write on tablet paper in the labored fifth-grade hand of a school child; others write on linen in the neatly feminine and classic lines that are surely
those of a school teacher; still others type on expensive letterheads that show the nature of their professions.
This circular is written for all of them but
especially for those of school age. It is for school teachers, scoutmasters, parents, and other counselors of children. It is a beginner’s guide to fossils, most useful to collectors in Indiana. It is for the curious everywhere who do not write to me, but who seek a hobby, avocation, or beginning knowledge to a profession.
It is for all who are interested and seek,
through fossils, one means to the Truth.

Fossils: Prehistoric Animals in Hoosier Rocks
Perry, Thomas G.
Fossils are abundant in Indiana’s rocks, and Hoosiers commonly seek information about these relics of ancient life from the Indiana Geological Survey. The primary purpose of this circular is to provide information on the principles of paleontology and the major kinds of fossils found in Indiana. Many of the fossils illustrated in this Circular are found in Indiana bedrock; some have been included to provide more information on the characteristics of the major groups of fossils. Another purpose is to stimulate interest in fossil collecting, a healthful pastime that may lead younger readers to a rewarding career. This account of ancient life concludes with a list of books that deal largely with fossils and earth history. Fossilized remains of primitive vertebrates are not discussed as they are rare in Hoosier rocks. Prehistoric plant life in Indiana is not considered, as Canright (1959) has recently described plants that grew in Indiana in the geologic past.
